cloud-init 0.6.2

0.6.2:
 - fix bug where update was not done unless update was explicitly set.
   It would not be run if 'upgrade' or packages were set to be installed
 - fix bug in part-handler code, that prevented working part-handlers
   (LP: #739694)
 - fix bug in resizefs cloud-config that would cause trace based on
   failure of 'blkid /dev/root' (LP: #726938)
 - convert dos formated files to unix for user-scripts, boothooks,
   and upstart jobs (LP: #744965)
 - fix bug in seeding of grub dpkg configuration (LP: #752361) due
   to renamed devices in newer (natty) kernels (/dev/sda1 -> /dev/xvda1)
 - make metadata urls configurable, to support eucalyptus in
   STATIC or SYSTEM modes (LP: #761847)
 - support disabling byobu in cloud-config
 - run cc_ssh as a cloud-init module so it is guaranteed to run before
   ssh starts (LP: #781101)
 - make prefix for keys added to /root/.ssh/authorized_keys configurable
   and add 'no-port-forwarding,no-agent-forwarding,no-X11-forwarding'
   to the default (LP: #798505)
 - make 'cloud-config ready' command configurable (LP: #785551)
 - make fstab fields used to 'fill in' shorthand entries configurable
   This means you do not have to have 'nobootwait' in the values
   (LP: #785542)
 - read /etc/ssh/sshd_config for AuthorizedKeysFile rather than
   assuming ~/.ssh/authorized_keys (LP: #731849)
 - fix cloud-init in ubuntu lxc containers (LP: #800824)
 - sanitize hosts file for system's hostname to 127.0.1.1 (LP: #802637)
 - add chef support (cloudinit/CloudConfig/cc_chef.py) (LP: ##798844)
 - do not give trace on failure to resize in lxc container (LP: #800856)
 - increase the timeout on url gets for "seedfrom" values (LP: #812646)
 - do not write entries for ephemeral0 on t1.micro (LP: #744019)
 - support 'include-once' so that expiring or one-time use urls can
   be used for '#include' to provide sensitive data.
 - support for passing public and private keys to mcollective via cloud-config
 - support multiple staticly configured network devices, as long as
   all of them come up early (LP: #810044)
 - Changes to handling user data mean that:
   * boothooks will now run more than once as they were intended (and as bootcmd
     commands do)
   * cloud-config and user-scripts will be updated from user data every boot
 - Fix issue where 'isatty' would return true for apt-add-repository.
   apt-add-repository would get stdin which was attached to a terminal
  (/dev/console) and would thus hang when running during boot. (LP: 831505)
   This was done by changing all users of util.subp to have None input unless specified
 - Add some debug info to the console when cloud-init runs.
   This is useful if debugging, IP and route information is printed to the console.
 - change the mechanism for handling .ssh/authorized_keys, to update entries
   rather than appending. This ensures that the authorized_keys that are being
   inserted actually do something (LP: #434076, LP: #833499)
 - log warning on failure to set hostname (LP: #832175)
 - upstart/cloud-init-nonet.conf: wait for all network interfaces to be up
   allow for the possibility of /var/run != /run.
 - DataSourceNoCloud, DataSourceOVF : do not provide a default hostname.
   This way the configured hostname of the system will be used if not provided
   by metadata (LP: #838280)
 - DataSourceOVF: change the default instance id to 'iid-dsovf' from 'nocloud'
 - Improve the OVF documentation, and provide a simple command line
   tool for creating a useful ISO file.
